Balloons

Put a small marble(glass beads work too) in a balloon(the ones that you make into animals are good as well as the regular) and insert it into your pussy or your ass then take a bike pump or if you're flexible your lips on the opening and blow it up then tie it. I like to go running or get on the trampoline afterwards because the marble works wonders as it bounces around and the best part is it can last up to a week before the air starts to empty. Plus the items are inconspicuous when your at the store next time pick up some balloons and some marbles or anything that looks like it wouldn't be painful to have bouncing around inside you.

Have fun with this ^__^
